Image Options

Property	Type	Description
src	string	Required. A string referring to any valid image resource (file, url, etc).
width	number	Required. Width of the image.
height	number	Required. Height of the image.
nano	string:base64	Optional. Thumbnail Base64 image will be injected to background under the main image. This provides a base64, 4x4 generated image whilst the image is being loaded.
alt	string	Optional. Image alt attribute.
tags	array	Optional. An array of objects containing tag attributes (value, title and key if value is element). e.g. `{value: "foo", title: "bar"}` or `{value: <a href={tag.url}>{tag.name}</a>, title: tag.title, key: tag.key}`
isSelected	bool	Optional. The selected state of the image.
caption	string \| ReactNode	Optional. Image caption.
customOverlay	element	Optional. A custom element to be rendered as a thumbnail overlay on hover.
thumbnailCaption	string \| ReactNode	Optional. A thumbnail caption shown below thumbnail.
orientation	number	Optional. Orientation of the image. Many newer digital cameras (both dSLR and Point & Shoot digicams) have a built-in orientation sensor. The output of this sensor is used to set the EXIF orientation flag in the image file's metatdata to reflect the positioning of the camera with respect to the ground (See EXIF Orientation Page for more info).

Gallery Options

Property	Type	Description
images	array	Required. An array of objects containing image properties (see Image Options above).
id	string	Optional, default `ReactGridGallery`. `id` attribute for `<Gallery>` tag. This prop may be useful for those who wish to discriminate between multiple galleries.
enableImageSelection	bool	Optional, default `true`. Allow images to be selectable. Setting this option to `false` whilst supplying images with `isSelected: true` will result in those images being permanently selected.
onSelect	func	Optional. Function to execute when an image is selected. Optional args: `index` (index of selected image in images array), `image` (the selected image), `event`. This function is only executable when `enableImageSelection: true`.
rowHeight	number	Optional, default `180`. The height of each row in the gallery.
maxRows	number	Optional. The maximum number of rows to show in the gallery.
margin	number	Optional, default `2`. The margin around each image in the gallery.
onClick	func	Optional. Function to execute when gallery image clicked. Optional args: `index` (index of selected image in images array), `image` (the clicked image), event (the click event).
tagStyle	func \| CSSProperties	Optional. Style or function that returns style to pass to tag elements. Optional args: `item` (the image item in `images`). Overrides internal tag style.
tileViewportStyle	func \| CSSProperties	Optional. Style or function to style the image tile viewport. Optional args: `item` (the image item in `images`). Overrides internal tileViewportStyle function.
thumbnailStyle	func \| CSSProperties	Optional. Style or function to style the image thumbnail. Optional args: `item` (the image item in `images`). Overrides internal thumbnailStyle function.
thumbnailImageComponent	React component	Optional. Substitute in a React component that would get passed `imageProps` (the props that would have been passed to the `<img>` tag) and `item` (the original item in `images`) to be used to render thumbnails; useful for lazy loading.
defaultContainerWidth	number	Optional. Set default width for the container. This option is useful during server-side rendering when we want to generate an initial markup before we can detect the actual container width.

General Notes

react-grid-gallery is built for modern browsers and therefore IE support is limited to IE 11 and newer.
As the inspiration for this component comes from Google Photos, very small thumbnails may not be the most aesthetically pleasing due to the border size applied when selected. A sensible rowHeight default of 180px has been chosen, but rowHeights down to 100px are still reasonable.
Gallery width is determined by the containing element. Therefore your containing element must have a width (%, em, px, whatever) before the gallery is loaded!
If you don't know your width and height values, you can find these out using any number of javascript hacks, bearing in mind the load penalty associated with these methods.
